Question:
Identify homopolymer from following.
Identify homopolymer from following.
Show Hint
The prefixes in polymer names often give away their nature! Names with multiple chemical parts (like Phenol-Formaldehyde or Nylon-6,6) are copolymers. Simple repeating names (like Poly-ethylene, Poly-propylene, Poly-tetrafluoroethylene) are homopolymers!

Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
We need to identify which of the given polymers is a homopolymer.
Step 2: Key Formula or Approach:
A homopolymer is a polymer synthesized from only one single type of repeating monomer unit.
A copolymer is synthesized from two or more different types of monomer units.
Step 3: Detailed Explanation:
Let's analyze the composition of each polymer:
(A)
Teflon (Polytetrafluoroethylene): Synthesized entirely from a single monomer, tetrafluoroethylene ($\text{CF}_2\text{=CF}_2$). It is a homopolymer.
(B)
Nylon 2-nylon 6: An alternating copolymer made from two different monomers: glycine and aminocaproic acid.
(C)
PHBV: A biodegradable copolymer made from 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.
(D)
Bakelite: A cross-linked condensation copolymer formed from phenol and formaldehyde.
Step 4: Final Answer:
Teflon is the only homopolymer among the choices, which matches option (A).
